Main Description



The included basic issues should be addressed to detail all requirements that are not specified within the use-case model.



Check Items




Functionality



What is the software supposed to do? This should include the following: Validity checks on the inputs General responses to abnormal situations, including: overflow, communication facilities, error handling and recovery Effects of parameters Relationship of outputs to inputs, including input/output sequences and formulas for input to output conversion



External interfaces



How does the software interact with people, the system's hardware, other hardware, and other software?



Performance



What is the speed, availability, response time, recovery time of various software functions, etc.? Are both static and dynamic requirements included?



Logical database requirements



Have all logical requirements been specified for any information that is to be placed into a database? This may include the following: Types of information used by various functions Frequency of use Accessing capabilities Data entities and their relationships Integrity constraints Data retention requirements



Standards Compliance



Have all requirements derived from existing standard and regulations been specified? How will this be traced?



Attributes



What are the reliability, availability, portability, correctness, maintainability, security, etc. considerations?
